Sudan II (1-(2,4-Xylylazo)-2-naphthol), also known as Solvent Orange 7, is a member of the Sudan family of hydrophobic fat-staining dyes. Sudan dyes are a group of lipid soluble solvent dyes often called lysochromes, in structural classification they are diazo dyes. With the use of certain solvents, may also be used to stain some protein bound lipids in paraffin sections. By studying the cellular regions where the dye is sequestered, Sudan II has been used it to evaluate how certain toxins interact with membranes.
